Fans of Bach and Haydn have perhaps suspected a kinship with the ornamental grandeur of 1970s-era glitter kids such as Queen and David Bowie-as-"Ziggy Stardust." But it's taken the Portland Baroque Orchestra and indie septet Sophe Lux to bring the two schools of thought -- separated by a mere 400 years -- together where they belong, as strange stylistic bedfellows who share a fondness for the sweeping dramatic gesture.

Wednesday's Baroque Bash at Holocene gives Classical Revolution PDX, a 37-member collective, a platform to perform works from many 17th- and 18th-century composers.

They'll do this alongside Portland's Sophe Lux, whose theatrically inclined frontwoman Gwynneth Haynes (younger sister of filmmaker Todd Haynes) applies her camp sensibility and octave-scaling soprano to music that bears as much in common with the rebellion of Kurt Cobain as it does the Weimar sophistication of Kurt Weill. The group's proclivity for powdered wigs and costumed refinery is only a sideshow when compared to the artistic growth of its sophomore release, 2007's terrific "Waking the Mystics," which flaunts a dozen tunes that can easily hold their own with other local stylistic seekers such as the Decemberists.

The Baroque Bash may not constitute a night tripping the light fantastic in Vienna, but for this DIY crew, it remains every bit as rich an experience.
